Two short bar magnets of magnetic moments 0.1245 Am^(2) and 0.512 Am^(2) are placed with their like poles facing each other. If the distance between the centres of the magnet is 0.26m . The distance of neutral point from the weaker magnet is

Two bar magnets A and B , each having a magnetic length of 4 cm are placed along a straight line with their north poles 8 cm apart and facing each other . The neutral point lies on the axis , 2 cm from the north pole of the magnet A . Calculate the ratio of the magnetic moments of A and B . [ Ignore the effect of earth ' s magnetic field ] .

Two bar magnets of magnetic moments 12Am^(2) and 10Am^(2) are placed one over the other .First with their similar poles in contact after unlike poles in contact.The ratio of their resultant magnetic moments is

Two short magnets of magnetic moment 2 Am^(2) and 5 Am^(2) are placed along two lines drawn at right angle to each other on the sheet of paper as shown in the figure. What is the magnetic field at the point of intersection of their axis?

Two short magnets of magnetic moment 2 Am^(2) and 5 Am^(2) are placed along two lines drawn at right angle to each other on the sheet of paper as shown in the figure. What is the magnetic field at the point of intersection of their axis?

Two short bar magnets have magnetic moments 1.20 Am^(2) and 1.00 Am^(2) respectively . They are kept on a horizontal table parallel to each other with their north poles pointing towards the south . They have a common magnetic equator and are separated by a distance of 20.0 cm. The value of the resultant horizontal magnetic induction the mid point O of the line joining their centers is (Horizontal components of Earth's magnetic induction is (3 xx 10^(-5) Wb m^(-2) ) ...............
